Title: Electronic device for the energization of an electromagnetic element
Inventor: BEULEN WINFRIED
IPC: H01H47/32
Filed: 1981-12-16
Abstract: Electronic device for the energization of an electromagnetic element, particularly a troke-coil or a coil of an electromagnetic switching apparatus having a magnetic circuit with a coil, a yoke and an armature. A comparator (5) receives a predetermined current order value U(I<usoll2>u) and an actual measured current value U (I<uist>u). Then the actual value goes down below the order value, the comparator (5) actuates, through a monostable flip flop element (6), a switching transistor (1) supplied by a supply voltage U<uv>u, arranged in the main current circuit of the electromagnetic element (2). After the constant conduction duration kin has elapsed, it blocks the transistor (1). With a variable conduction duration kin of the switching transistor (1), there results a variation of the current order value, function of the set conduction duration. In order to obtain a reliable operating mode of an electromagnetic switching apparatus comprising a coil, there is established a high actuation current order value and, after operation of the switching apparatus, a reduced maintaining current order value. For the operation of different switching states of the switching apparatus, the coil inductivity is taken into account.

Title: Temperature transducer
Inventor: ANDREWS DAVID JOHN
IPC: H01H37/32
Filed: 1983-01-24
Abstract: A temperature transducer is constituted by a coiled length of SME alloy, e.g. a copper-zinc-aluminium alloy.

Title: Semiconductor laser
Inventor: FUJIMOTO AKIRA
IPC: H01S5/028
Filed: 1983-08-12
Abstract: A semiconductor laser has at least one double heterojunction construction comprising an active layer, e.g. 5a, sandwiched between adjacent layers 4a, 4b, the layers being terraced and dopant being diffused from one surface of the semiconductor crystal to form a p-n junction 10a in the stepped region of the active layer. In a semiconductor crystal having a plurality of double heterojunction constructions (as in Fig. 3), the laser output can be shifted one PN junction to an adjacent PN junction, and the carrier injection electrodes have applied thereto a voltage for initially setting the PN junctions to a state slightly below the laser oscillation threshold value, and further a laser beam is adapted to be directed upon one of the PN junctions from the outside of the semiconductor crystal to photoexcite the PN junctions to create laser oscillation. <IMAGE>

Title: Roof ventilation
Inventor: MARSHALL CLIVE ROBERT WILLIAM
IPC: E04D13/17
Filed: 1983-09-30
Abstract: A roof ventilation device in the form of an elongate unit (11) defines a ventilation slot such that a row of such units, mutually aligned and secured along the eaves of a roof structure can provide for the passage of ventilation air into the roof space to minimise the risk of condensation. Each unit has upper and lower web members (2, 3) spaced apart to define the slot and means, such as a row of vertical fins (15), to subdivide the ventilation slot into a multiplicity of ventilation apertures through which the ventilating air must pass. The grill-like structure prevents birds and small animals entering the roof space. A gauze strip (7) may be provided across the rear face of the unit. The row of ventilating units can be fixed on top of a facts board (14) or the upper course of bricks supporting the edge tiles. The upper web member (2) of each unit preferably projects forwardly of the corresponding edge of the lower member in order to prevent the outer strip portion (18a) of roof lining felt (18), which projects over the units, from sagging so as to shut off the ventilation apertures. <IMAGE>

Title: Vaccine against parasitic protozoa
Inventor: DAVIS PAUL JAMES
IPC: A23K1/00
Filed: 1984-08-03
Abstract: An oral vaccine against parasitic protozoa, such as coccidia, comprises live encysted protozoa embedded in a firm gel matrix from which the protozoa are released following ingestion by a host. The gel matrix helps to maintain the essential viability of the protozoa without seriously hindering the natural mechanism by which they infect their host. Preferably the gel matrix is based on alginate. Alginate beadlets containing viable sporulated coccidia oocysts, for administration to poultry, are a preferred feature.
Patent GB-2163363-A (GB)
Title: In situ reforming catalyst regeneration
Inventor: BUSS WALDEEN C
IPC: B01J23/96
Filed: 1984-08-22
Abstract: A process is disclosed for regenerating reforming catalysts containing a platinum component and a rhenium component preferably in association with a halogen component on a porous alumina without significant displacement of the rhenium component by sulfur oxides generated during the regeneration process. The process is particularly characterized in that carbon is removed from the catalyst by in situ oxidation at temperatures not in excess of 399 DEG C and without modification of the catalytic reforming process flow circuit, as by disconnecting or isolating the heat exchangers and furnace tubes. Sulfide scale is converted in a separate oxidation step to sulfur dioxide, SO2, without substantial oxidation to sulfur trioxide, SO3, by maintaining the inner walls of the heat exchangers and furnace tubes, where such iron sulfides are present, at a temperature not in excess of 482 DEG C and not less than 399 DEG C and under regenerating conditions including a low oxygen concentration. The sulfur dioxide then passes through the reforming catalyst without effectively displacing rhenium components from the carrier base. Further, by removal of these sulfides, complete regeneration of the catalyst is facilitated for subsequent redistribution of the platinum component at temperatures in excess of 399 DEG C, particularly when accompanied by halide addition.

Title: Apparatus and process for transferring a pattern to arcuate surface portions of a cylindrical object
Inventor: DEE RICHARD DIGIACOMO
IPC: B41F15/08
Filed: 1985-01-14
Abstract: An apparatus for transferring a pattern to a cylindrical object e.g. a bottle, is provided which eliminates the need for individually chucking each object, thereby significantly decreasing production time. The need for a squeegee to transfer the paint or dye onto the cylindrical object is also eliminated, resulting in longer screen life and further decreasing production time. A process for using this improved apparatus is also provided for. A non-absorbent support device (24) underlies screen (54) and both remain stationary during printing. Advancing means (38) e.g. continuous belts, continuously roll the objects across screen (54) away from the end (56) of support device (24) at which paint is introduced. This arrangement is such that the cylindrical object, as it is advanced, itself forces paint to advance across the support device (24) and through the screen (54) and to be transferred onto arcuate surface portions thereof to form said pattern. <IMAGE>

Title: Process for making a hard gasified sweet
Inventor: FABBRO ORESTE
IPC: A23G3/00
Filed: 1985-08-23
Abstract: The gasified sweet with a spherical shape or any other regular or irregular shape, incorporating or not incorporating a stick of plastic or other suitable material, and producing small popping noises resembling the bursting of the bubbles in gasified drinks, is obtained continuously and automatically by means of machines for the formation of the caramel stick, for calibration and stamping-out, optionally with introduction of the stick, and for cooling, which are subjected to pressurisation at certain pressures greater than atmospheric pressure, and preferably between 10.1525 and 81.06 bar. The successive stages of the process take place continuously inside pressurised containers, from the instant when the molten and gasified caramel mass is present in the initial container until the instant when the gasified sweet with a stick is completely crystallised, its internal temperature being below 30<o>C. Due to the fact that the occluded gas ruptures the protective film when the hard sweet is consumed, the latter produces, in a uniform and continuous fashion, a hissing resembling the popping noises produced by the bursting of the bubbles in refreshing, gasified drinks, without producing strong cracks which would break the piece of confection attached or not attached to the stick.
